Every day, companies compete for a limited resource: your attention.Every day, companies compete for a limited resource: your attention. This book examines how that competition works, tracing the economic incentives, technologies, and design choices that shape the media and platforms you use. Generated by an artificial intelligence, this book draws on publicly available research and reporting to explain how attention became a measurable, tradable commodity. You will learn how advertising markets developed, how algorithms are built to hold engagement, and how businesses profit from the time you spend online. The book also looks at the other side of this system, including regulatory responses, design ethics, and personal strategies people use to manage focus in an environment built to capture it. Written for general readers, this is an introductory guide to understanding the mechanics behind modern distraction, not a call to alarm but an invitation to see the system more clearly.Every day, companies compete for a limited resource: your attention.
